Struct ConvertStats 

pub struct ConvertStats {
    pub src_imports: u64,
    pub src_pbo_uploads: u64,
    pub src_uploads: u64,
    pub zero_copy_declines: u64,
}

Per-processor zero-copy telemetry: how convert sources reached the GPU and how often a zero-copy opportunity was declined into a copy path.

This is deliberately SEPARATE from GlCacheStats: that struct is the steady-state import-cache equality gate (tests assert exact equality on it), while these counters change on every convert. src_uploads staying at 0 across a Dma-source workload is the “no silent zero-copy drop” assertion callers (and the on-device validation harness) can make — EGLImage miss counts alone are blind to uploads.

Fields

src_imports: u64

Sources fed zero-copy: the tensor’s Dma buffer became the sampled texture’s storage (EGLImage attach / IOSurface pbuffer bind).

src_pbo_uploads: u64

Sources fed from a PBO (GL-internal copy, no CPU visit).

src_uploads: u64

Sources fed by CPU map + TexImage upload — the copy path.

zero_copy_declines: u64

Times a zero-copy source feed was attempted and DECLINED into a copy path (import/attach failure). A nonzero value with Dma sources means the platform/driver refused the fast path.
